The following juvenile survival queries allow users to look up (1) CSS juvenile river reach survival estimates; (2) the number of fish used in the CSS analysis by source site; (3) CSS SR, TIR, and D parameters; and (4) FPC annual report survival estimates (includes SMP and CSS program data).

- Allows the user to query in-river smolt survival rate estimates through the hydrosystem for PIT-tagged wild and hatchery Chinook and steelhead. The in-river smolt survival estimates were calculated using the CJS method.

The majority of the Smolt Monitoring Program (SMP) survival estimates are calculated for evaluation of hydrosystem effects in particular reaches on aggregate PIT-tag populations. These aggregates incorporate all available PIT tags to estimate survival for the run-at-large. Reach survival estimates are divided into short time intervals so that environmental effects such as flow, spill and temperature can be evaluated in relation to survival. Additionally in a few cases, survival is estimated for specific SMP releases of interest such as from large traps or other smolt monitoring facilities (e.g. Snake River Trap or Rock Island Dam). Releases from these specific sites of interest are on an annual smolt migration basis.
